Why Choose the RF825000?
Keep three-phase motors protected with the Lovato RF825000 thermal overload relay. This three-pole, phase failure/single-phase sensitive unit covers 35…50 A and features manual resetting for controlled restarts. Designed for direct mounting on BF40–BF94 contactors, it streamlines panel assembly and simplifies coordination in Lovato BF motor starter combinations.
Engineered for demanding environments, the RF825000 offers Ui 690 V and Uimp 8 kV, IP20 frontal protection and pollution degree 3. It operates from -20 to 55 °C and up to 3000 m altitude, supporting reliable performance in control panels. Conforms to IEC/EN 60947-1 and 60947-4-1, UL508 and CSA C22.2 n° 14 for global compliance.
